Step-by-step explanation:
Y= x - 2. Y = 3x + 5
Putting value of y 
x - 2 = 3x + 5
-2 - 5 = 3x - x
-7 = 2x 
-7/2 = x 
Putting value of x 
Y = 3(-7/2) + 5
Y = - 10.5 + 5
Y = - 5.5

Answer:
3 hours
Step-by-step explanation:
$12 = 2hours
Find how much Clare was paid for one hour
Total money earned ÷ number of hours = wage per hour
12 ÷ 2 = $6 per hour
set up equation 
6x = 18
This equation says 6 dollars an hour × number of hours = $18
To solve for this equation, divide both sides by 6 (this isolates the variable)
6x ÷ 6 = 18 ÷ 6
1x = 3
x = 3
